Helped navigating through the busy stations without losing the group.
Alex was an excellent guide, checking regualrly if we needed a comfort break, etc. Also, he is so knowledgeable, the tour he put together for us was excellent, ticking off so many things we had on our 'to do' list that it left us time on our remaining days to explore HK at a leisurely pace.
Jill was fabulous. She took us to see the shopping experiences I hope to see and added some history and culture along the way. It was a great way to learn more about Paris and how walkable the city is.
